SPENCER c. CARY, or BnooKnYn, NEW YORK.

snrrrme-casn Application filed October 27,1911, Serial No. 657,077.

To all whom it may concern:

Be it known that I, SPENCER C. CARY, a citizen of the United States,residing in the city of New York, borough of Brooklyn, county of Kings,and State of New York, have invented a certain new and usefulShipping-Case, of which the following is a specification.

This invention is a case for shipping various articles, moreparticularly contamers for Oll and the like.

It is a common practice in the transportation of oil, or other liquids,to place the same 111 cans of about five gallons (5 gals.) capaclty, andto lncase two of said cans within an inclosing package of one form oranother, said casing being composed usually of walls of wood or woodveneer nailed together and bound with metal box strapping.

By reason of the weight of the cans, a wooden casing having its wallsnailed together is too frail to successfully withstand the strain of theweight and the handling to which the package is subjected. To-

strengthen the case, it has been customary to employ metal boxstrapping, composed of wire or sheet metal, but even this expedient hasbeen foiuid unsatisfactory. As a result there exists a demand 'for astrong, durable and economical packing case, especially adapted for thetransportation of heavily loaded oil cans, and to meet this demand isthe object of this invention.

In carrying out the invention, 'I- employ a sheet of metal of the sizeand form required to form the bottom, side walls and top of the packingcase. This sheet'is prepared in advance of the operation of assemblingit with wooden end walls to complete the inclosure for a plurality ofoil cans, the preliminary preparation of the metal sheet consisting incutting it to the form and dimensions required and, also, in' subjectingthe sheet to the action of a powerful press in order to emboss the sheetat certain defined places for the purpose of producing panels in saidsheet. The

the sheet, and inwardly thereof, and they serve the purposes of stays inrendering the sheet strong and stiff enough to resist the weight andpressure of the filled cans, the latter being adapted to contact withthe pressed-in portions of the panels. i Vhen'the cans are to beincase'd, a prepared metal' Specification of Letters Patent.

sheet into overlapping relation and by fastening the lapping edges, asby riveting them together.

The invention embodies, also, means for separating the two cans adaptedto be inclosed within thecase- In one form of construction, the bottomof the sheet metal case is doubled to produce a rib between certainpanels, but in another form I employ a stay made separate from the sheetmetal blank. The stay is composed of strong:

strap metal positioned in contact with the bottom, sides and top of thesheet metal case, the end portions of the stay being inserted throughthe lapping edges of the sheet metal, and then bent upon said edges. Thestay operates as a separator for the cans, and it adds materially to thestrength and rigidity of the sheet metal, so as to preclude to a largeextent the tendency of the sheet'metal to bend and buckle when the caseis struck by an outside blow.

Other features of the invention and the advantages thereof will appearin the course of the following description taken in connection with thedrawings. V

In the accompanying drawings, I have illustrated difierent practicalembodiments of the. invention, but the constructions shown therein aretobe understood as illustrative, only, and not as defining the limits ofthe invention. r

Figure 1 is aplan view ofa metal blank adapted to be bent so as to formthebottom, sides and top of a shipping case in accordance with thisinvention.

Fig. 2 is a vertical cross section through a shipping case, the body ofwhich is formed by the blank of Fig. 1.

Fig; 3 is a longitudinal section on the line 3-3'of Fig. 2.

Fig. 4 is a plan view of another'form of blank embodying the generalfeatures of the blank shown in Figi 1, and in addition thereto saidblank of Fig. 4 is provided with an integral rib on the bottom of the resulting case, which rib acts as a separator for containers or cansadapted to be inclosed by the case.

Figs. 5 and 6 are a vertical cross section and a vertical longitudinalsection of the shipping case having its body composed of the blank shownin Fig. 4:.

Fig. 7 is a plan view of another form of blank adapted toforin the bodyof the shipping case.

Figs. 8 and 9 are views in vertical cross section and verticallongitudinal section, respectively, of a packing case body resultingfrom the employment of the blank of Fig. 7.

Fig. 10 is a plan of a pressed metal blank embodying the panelconstruction of Fig. 1 and the flanged and slotted construction of Fig.7 whereby the resulting metal case is adapted for the reception of thestay strap disclosed in Figs. 8 and 9.

Figs. 11 and 12 are cross sections of the metal case resulting from thebending of the blank shown in Fig. 10 and the use of the stay strap inconnection therewith.

The body of the packing case is produced by bending a blank, A, of sheetmetal at a number of points to form the bottom, sides and top. Thisblank consists, preferably, of a single piece of sheet metal having therequired form and dimensions. The blank is adapted to be bent ontransverse lines indicated at a, 7), o, and (Z, and, if desired, thelines of bend may be indicated in any desired way on the sheet metalblank, as for example, by score marks, perforations, upset portions ofthe metal, etc. The bottom of the shipping case is adapted to beproduced by that part of the blank between score lines, a and Z). Oneside wall of the case is formed by that part of the blank between 5 and(Z. The other side wall of the case is produced by that part of theblank between lines a and c, and the top of the case is formed bybringing the end portions of the blank into lapping; relation.

For the purpose of stiffening the body of the case, and of impartingsuflicient rigidity to said case to withstand the weightof the contentsand the strain of handling the case. the body portion thereof isprovided with a number of panels which are produced in the sheet metalblank prior to the operation of bending it to form the case. As shown,the bottom portion of the case is provided with a series of panels, B,preferably, four in number: each side wall has a plurality of panels. C,two of said panels being provided on each side wall, and the top of thecase, produced by the meeting ends of the blank. is provided withpanels, 1), preferably two in number. The sheet metal blank, A. is cutvto the required form and size, and then it is placed in a. powerfulpress, which operates upon the sheet for the purpose of pressing ordisplacing the metal so as to result in the formation of the panels,substantially as hereinbefore described. The panels extend transverselyof the sheet metal blank, but they terminate within the side edges ofthe sheet, or the open ends of the resulting case body.

While I have shown and described the bottom of the case as having fourpanels, and the side of the case as having two panels each, it will bemanifest that the number and arrangement of the panels may be variedwithin wide limits. It is deemed preferable, however, to provide thebottom of the body with a sufiicient number of panels which will securevery great strength and stiffness at the place where the case issubjected to the greatest strain. Furthermore, the panels, C, on thesides of the case serve to stiffen the body so as to prevent the casefrom bending or buckling under the effect of blows which strike theoutside of the case.

It will be understood that a desired nunh ber of sheet metal blanks, A,may be rapidly and economically produced from sheet metal at a factory,and prior to the operation of making the shipping ease. The pieces ofsheet metal are prepared in any suitableor desired way by cutting thesheets to the required form and dimensions, and thereafter subjectingthe sheets to pressure in a suitable press which will eniboss the sheetsso as to produce the sanels, B,-C, and D thereon. The sheets having beenprepared as d scribed, they are packed in a flat condition so as to beshipped economically from the factory to the place at which it isdesired t convert them into packing cases.

lVhen it is desired to make a packing case, a sheet metal blank, A, isbent or folded on the lines a, 6,0, and (Z, thus producing asubstantially rectangular inclosure or body, shown in Figs. 2 and 3, theends of said body being open. he operation of bending the sheet havingbeen completed. the end edges ofthe sheet are brought into lappingengagement as shown in Figs. 2 and 8, said end edges being attachedtogether if desired, although this is not essential. It now only remainsfor the operator to apply the end closures or sections, E, F, to theopen end of the sheet metal body. An end closure or section, E, isadapted to be placed in one end portion of the sheet metal body, and tobe secured to said body by suitable fasteners. such the nails, 6, or ifdesired, screws or other fasteners may be substituted therefor. Thefilled cans or containers may now be placed within the body so as torest upon panels, B, of the bottom, and thereafter the other end closureor section, F. should be positioned within the opposite open end of thesheet metal body, said end closure or section, F, being secured inposition by nails,

screws, or other devices, f, all as shownin Fig. 3.

It will be noted that the sheet metal body is adapted to be easily andquickly bent, and the end closures or sections, E, F, may be easilyplaced into position and secured to the end portions of the body. Eachend section may be composed of wood or other material, in one piece, ifdesired. The employ ment ofthetwo sections or closures adds to thestiffness and strength of the resulting case. The edges of the sheetmetal body are fastened firmly to rigid end pieces,the fastenings beingapplied to the bottom, sides and topof the packing case. The lappingends of the sheet metal'blank may be riveted together, or the sideedgesQofthe blank may be attached to the end sections at the top of thecase, as shown in Fig. 12.

Another way of making the case is to bend the blank along lines,'a, b,so as toproduce the bottom and upstanding sides, and to then positionthe rigid end pieces, E, F, at the open ends of the sheet metal body,and finally the sheet metal and the wooden end pieces are fastenedtogether, leaving-those portions of the tophaving panels, D, extendingupwardly from the package, The oil cans or the containers are now placedwithin the package, and finally the top portions of the blank are bentalong the lines, 0, (Z, so that their free edges will overlap, therebycompleting the top, which top is fastened to the upper edges of endsections, E, F, whereby a completely closed case is produced forenveloping the oil cans or other containers.

It will be observed, by reference to Figs. 2 and 3, that panels, B, C,D,- extend inwardly with respectto the case. Panels, B, engage with'thebottom of the oil cans or containers; panels, C, engage with the outersides of the oil cans or conta.iners;'and panels, D,- rest upon the topends of the oil cans, whereby the cans do not contact directly with themetal of the :blank forming the body but are limited to engagement withthe inwardly extending panels;

Sheetmetal blank, A, of F ig, 4 is similar in all substantial respectsto the blank, A, of Fig. 1, that is'to say, said blank, A, is providedwith panels, B, C, D, and it is adapted to be bent or folded on thelines, a, b, 0, (Z, respectively. In addition to the panels, blank A. isprovided with means adapted to separate the two oil cans or containerswhich are to be placed within the packing case. Said separating meansconsists of a rib, G, provided on that portion of the blank which formsthe bottom of the body. The rib is produced by folding or bending themiddle part of the blank upon itself. whereby the rib is made integralwith the sheet metal" blank. The rib extends transversely across theblank, and it is posi- B, of the bottom. As shown in Figs. 5 and 6, therib extends inwardly above the bottom and above the panels, B, thereof.Y

The mode of making the body by bendingthe blank on the lines, a, b, ofsecuring ployment oftherib adds additional strength or stiffness to thebottom of the packing case, but the primaryoffice of said rib is toseparate the cans or containers adapted to be placed within the case.Therib acts to con fine one can between itself and the panels at oneside wall of the case, and to serve a like purpose in retaining theother can between the other side wall of the case, whereby the ribacts-to preclude sliding displacement of the two cans within theshipping case.

In Figs. 7, 8 and 9 of the drawings, I have illustrated anotherembodiment of the invention, wherein the body of the case is formed by asheet metal blank, A adapted to be bent or folded on the lines, at Z2 (Zso as to produce a sheet metal body, the ends of which are closed bysolidpieces', E F the latter being secured in position by nails,

screws or other fasteners to the side edges offlanges, g. The flangesare adapted to be embedded or inserted into the edges of end pieces. E Fas shown in Fig. 9, whereby the sideedges of the sheet metal blank areattached firmly to the rigid end pieces. The

flanged side edgesare thus embedded in the end pieces, which precludethem from pro- 1ect1ng beyond the end pieces, thus overcoming anytendency of cutting the hands of the operatorwhen handling the heavypacking case.

In connection with blank, A there is employed a stay, H, composed,preferably, of flat or strap metal. The metal of the stay piece isseparate from the sheet metal blank adapted to form the body. and thisstay piece is shown as being positioned within the sheet metal body.The-stay piece is bent to conform to the interior shape and dimensionso-fthe body. and the ends of said stay piece are attached the lappingtopportions of the sheet metal body. The attachment of the end portionsof the stay to the lapping portions of the sheet metal body may beeffected in various ways, but in the said end portions, the slots, i,thereof slip over upstanding portions, it, of stay H. After closingthetop of the case in the manner described, the end portions of stay H arepassed through slots, 2', and are bent or doubled upon the top, as shownat 7t in Figs. 8 and 9, whereby the ends of stay, H, are united rigidlyto the lapping portions of the top. This construction produces a strongand substantial closure for the top of the case, and the case is sosecurely closed that it cannot be opened or tampered with withoutleaving some evidence of the attempt to open the case.

The employment of stay, H, within the packing case serves two purposes:first, the stay increases the stiffness and rigidity of the bottom,sides and top of th case itself, and said stay serves the additionalpurpose of a separator for the cans or containers adapted to be packedwithin the case, the stay thus serving the primary purpose of rib. G, inthe construction of Figs. 4:, 5 and 6.

In Figs. 10, 11 and 12 of the drawings there is shown a metal caseformed by a metal blank A pressed to produce the pair els B C 1) similarto Fig. 1, which blank A is flanged at the edges, as at 9 and the endsof which are slotted at The blank is bendable as heretofore described toproduce the bottom, sides and top of the case, the rigid end pieces Eare secured within the box by nailing the parts and by embedding theflanges into said end pieces, and the box is interiorly stayed by ametal strap H the latter being positioned in contact with the bottom,sides and top as described in connection with the metal case of Figs. 8and 9. The ends of stay H are inserted through the slots 2' when theparts forming the top are brought into lapping relation, after whichsaid ends of the stay are bent to securely fasten the lapped meetingparts of the top, said interiorly positioned stay acting as a separatorfor the cans placed within the metal box,

Under some conditions the panels, D, D, of the blanks shown in F igs'land 4; may be constructed so that one panelwill enter the other panelwhen the end edges of the blanks are brought into overlapping engagementwhen folding said blank to complete the top of the case. It is thoughtthat the operation and advantages of theinvention will be understood bythose skilled in; the art, from the foregoing description taken inconnection with the drawings. The sheet metal blank .of one form oranother, may be easily and quickly-prepared, and all the blanks may beplaced one upon the other so as to take up very little room whenpacking, shipping and storing the metal. llhe packing case may be easilyand quickly formed by bending the blank as described, andby attachingthe rigid end pieces to the bent up body resulting from the bending ofthe blank. The case is simple and strong in construction, and it iseconomical to manufacture. The case is stayed or reinforced to withstandthe weight of the packages to be inclosed therein, and said case is notliable to become broken or materially injured when handling the same.The employment'ot the stay, 'H, is a yerymaterial advantage for thereason that said stay not only separates the oil cans or containers, butit adds materially to the stiffness and rigidity of the walls of thesheet metal body, besides a'liording very convenient means for securelyclosing the top of the case.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent is t l. A shipping crate embodying ablank composed. of sheet metal scored and bendable on predeterminedlines to produce a body of case, said blank being. embossed transverselyto form parallel panels throughout'the central part thereof and to leavea marginal, edge of the blank ree from embossing. the marginal edgesbeing provided with flange, end closures posi tioned within the openends of the body produced by bending the blank, the flanges beingembedded in the end closures, and means I passing through said marginaledges of the blank into the end closures for securing the end closuresfixedly to the body.
